Abstract (en)

[origin: US2023198515A1] A switch including a transistor to be protected, and a Miller effect protection unit including a protection transistor, the drain of the protection transistor being connected to the gate of the transistor to be protected, the source of the protection transistor being connected to the source of the transistor to be protected, a linking circuit, the linking circuit being a high-pass filter arranged between the gate of the protection transistor and the drain of the transistor to be protected, and a control circuit interposed between the gate of the protection transistor and the source of the transistor to be protected.

Abstract (fr)

La présente invention concerne un commutateur (10) comportant :- un transistor à protéger (12), et- une unité de protection (14) contre l'effet Miller comprenant :- un transistor de protection (18), le drain (180) du transistor de protection (18) étant relié à la grille (12G) du transistor à protéger (12), la source (18S) du transistor de protection (18) étant reliée à la source (12S) du transistor à protéger (12),- un circuit de liaison (20), le circuit de liaison (20) étant un filtre passe-haut disposé entre la grille (18G) du transistor de protection (18) et le drain (120) du transistor à protéger (12), et- un circuit de commande (22) intercalé entre la grille (18G) du transistor de protection (18) et la source (12S) du transistor à protéger (12).
